Observational Study Regarding Two Bonding Systems and the Challenges of Their Use in Orthodontics: An In Vitro Evaluation

The purpose of this in vitro study was to analyze and identify a methodology for the improvement shear bond strength orthodontic brackets bonded with two adhesive systems considered be widely used, Transbond Plus Color Change Self-Etching Primer Fuji Ortho LC orthophosphoric acid under various enamel conditions: dry, moistened water saliva. sample size included group 120 freshly extracted premolars distributed into six groups, each one 20 teeth. A universal testing machine used detach brackets. We determined compared studied different surface conditions. mean values groups 1 (TPCC, TSEP, dry), 2 water), 3 saliva), 4 (Fuji LC, etched, dry enamel), 5 etched enamel, water) 6 saliva) were 15.86, 12.31, 13.04, 15.27, 14.14 13.11 MPa, respectively. ANOVA test Student’s t-test showed significant differences between groups. While clinically acceptable strengths obtained all particular outcome that authors’ knowledge has not been documented elsewhere obtained: case contamination, it is preferable use instead Plus.
